Answer:
To calculate the heat required to convert water to steam, we can use the formula:
q = m * ΔHvap
where q is the heat required, m is the mass of water, and ΔHvap is the heat of vaporization.
First, let's calculate the mass of water in moles:
moles = mass / molar mass
The molar mass of water is approximately 18.015 g/mol.
Next, we can calculate the heat required using the equation:
q = moles * ΔHvap
The heat of vaporization for water is approximately 40.7 kJ/mol.
Let's plug in the values:
mass = 2.18 g
molar mass = 18.015 g/mol
ΔHvap = 40.7 kJ/mol
Now, we can calculate the heat required.
